Can ancient civilians buy land?

Ancient civilians were not allowed to buy maps. In China, the map was regarded as a symbol of power and a political means from the beginning, thus becoming the patent of the rulers. Daily governance and territorial expansion can not be separated from maps, and soil cracking can not be separated from maps. Because of this, not only ordinary people have no access to maps, but also high-ranking officials and dignitaries, and owning maps may also be suspected of rebellion. Business travel guides after the Ming and Qing Dynasties generally only have words. Until today, contour lines are not allowed on ordinary maps, and maps with a slightly larger scale are classified as internal or confidential.
